1. Field of the Invention
The present invention relates to a pneumatic particulate dispensing system for use in connection with the pneumatically dispensing of particulate material, such as fertilizers, seeds, pesticides, herbicides and insecticides. The pneumatic particulate dispensing system has particular utility in connection with providing a portable device for pneumatically dispensing particulate material.
2. Description of the Prior Art
Pneumatic particulate dispensing systems are desirable for distributing particulate material, such as corn, protein, food, fertilizers, seeds, pesticides, herbicides and insecticides through a singe portable device which can be easily mounted to a frame hitchably attachable to a vehicle. In current particulate dispensers, dispensing of particulate material is performed using complex and expensive devices using blower units, hoppers, and discharge tubes. Such devices use complex valve assemblies to adjust the flow of particulate material from the hopper to the passing airflow from the blower unit. Furthermore, these known particulate dispensers are not easily assembled or transported, which adds to the time required by the user to assemble, transport, use, and disassemble the dispensing device. Particulate dispenser users would quickly recognize that a system for quickly and easily dispensing particulate material in remote locations is very beneficial to the industry.
Additionally, other knows methods of hunters dispensing or filling feeders with particulate material is by packing feed sacks or buckets of feed up a ladder and then dumpling the feed from the sacks or buckets into the feeder. This method is inherently dangerous to the hunter, as well as strenuous and time consuming.
The use of hopper fed air powered granule dispensers is known in the prior art. For example, U.S. Pat. No. 5,156,102 to Andersen issued on Oct. 20, 1992 discloses an air powered granular material sowing apparatus having a blower connected to a tapered injector which forces air past a grain filled hopper. The air forces the grain towards a discharge tube.
U.S. Pat. No. 4,583,883 to Jahanning issued on Apr. 22, 1986 discloses a pneumatic conveyor having a pneumatic blower attached to a container featuring a hopper that dispenses grain into the airflow path via a bucket wheel. The grain from the bucket wheel is then discharged through an upright conveyor tube or a horizontal conveyor line.
Similarly, U.S. Pat. No. 4,221,508 to Haines issued on Sep. 9, 1980 discloses a forage harvesting towing vehicle having a blower attached to discharge tube, wherein the forage harvesting vehicle is attachable to a vehicle hitch assembly.
Additionally, U.S. Pat. No. 4,846,608 to Sanders discloses a pneumatic grain conveyor having a blower which forces air past a plurality of hoppers that dispenses material stored in the hopper into the airflow path from the blower. The material is dispensed from the hoppers through a control gate assembly located above a venturi.
U.S. Pat. No. 3,314,732 to Hagan discloses an insulation blowing apparatus whereby the insulation is drawn from a hopper by a fan and then blow into a conduit having a valve.
U.S. Pat. No. 4,821,495 to De Buhr et al. discloses a blower and discharge spout assembly having a blower connected to a fitting which is connected to an elevated discharge spout.
Lastly, U.S. Pat. No. 6,142,714 to Montag discloses a particulate material conveyor having a hopper attached to a power auger which conveys the particulate material to a fan which forces the particulate material through a conduit allowing a user to fill a receptacle.
Additionally, further examples of known pneumatic material dispensers are found in U.S. Pat. No. 4,988,240 to Thompson; JP 08215589 to Soichi et al.; and JP 2002068473 to Shigeru. While each of these systems may provide devices for dispensing material, they do not teach the use of a portable device for pneumatically dispensing particulate material fed by a hopper through a rotatable gate valve connected to a T-fitting which encloses a velocity tube.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a pneumatic particulate dispensing system having an air blower connected to a velocity tube via an adapter, which allows for the use of a variety of different air blowers, wherein the velocity tube creates a vacuum that removes the particulate material from an above mounted hopper through an adjustable rotary valve. Furthermore, the above-described devices make no provisions for a rotary valve that is connected to a T-fitting which encloses the velocity tube, wherein the rotary valve extends into the hopper, and whereby the entire system is supported by cradles mounted to a support frame adapted to inserted into a vehicle trailer hitch.
Therefore, a need exists for a new and improved pneumatic particulate dispensing system that can be used for a portable device for pneumatically dispensing particulate material. In this regard, the present invention substantially fulfills this need. In this respect, the pneumatic particulate dispensing system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of pneumatically dispensing particulate material through the use of a portable device.
In view of the foregoing disadvantages inherent in the known types of hopper fed air powered granule dispensers now present in the prior art, the present invention provides an improved pneumatic particulate dispensing system, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved pneumatic particulate dispensing system and method which has all the advantages of the prior art mentioned heretofore and many novel features that result in a pneumatic particulate dispensing system which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
To attain this, the present invention essentially comprises a particulate material container, such as a hopper, for storing particulate material therein. A fitting connected to the particulate material container, wherein the fitting is hollow and in fluid communication with the particulate material container. A conduit adapter is connected to the fitting and is adapted to connect a variety of air blowing units to the fitting, wherein the conduit adapter is in fluid communication with the fitting. A valve is connected to the fitting and the particulate material container for controlling the amount of particulate material that is transferred from the particulate material container to the fitting. A discharge tube is connected to the fitting.
The present invention is mounted on support frame having at least one cradle for supporting the air blower and the discharge tube. The frame support has a hitch member for supporting the frame from a vehicle hitch assembly.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
The invention may also include a velocity tube for creating a vacuum below the hopper for pulling particulate material from the hopper into a discharge tube which can be articulated with respect to the velocity tube. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the present invention when taken in conjunction with the accompanying drawings. In this respect, before explaining the current embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved pneumatic particulate dispensing system that has all of the advantages of the prior art hopper fed air powered granule dispensers and none of the disadvantages.
It is another object of the present invention to provide a new and improved pneumatic particulate dispensing system that may be easily and efficiently manufactured and marketed.
An even further object of the present invention is to provide a new and improved pneumatic particulate dispensing system that has a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such pneumatic particulate dispensing system economically available to the buying public.
Still another object of the present invention is to provide a new pneumatic particulate dispensing system that provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Even still another object of the present invention is to provide a pneumatic particulate dispensing system for dispensing particulate material through a portable pneumatic device. This allows a user with an easy and lightweight system for adjustably dispensing particulate material over a large surface or into an overhead receptacle. The system can be used by a single hunter, for example, for filling overhead animal feeders. The off the shelf components allows the pneumatic particulate dispensing system to be easily assembled and transported to any desired located by mounting the system on a support frame which is adapted to be inserted into a standard vehicle hitch.
Lastly, it is an object of the present invention to provide a new and improved method of dispensing particulate material using a portable pneumatic dispensing system. The user would adjust a rotary valve located in a hopper to the desired dispensing amount, and then fill the hopper with the particulate material that is to be dispensed. A pneumatic device would then be activated providing air flow below the rotary valve, thereby creating a vacuum for pulling the particulate material from the hopper into a discharge tube. The user would then attach a discharge nozzle to the discharge tube, wherein the discharge nozzle can be stationary or articulating.
These together with other objects of the invention, along with the various features of novelty that characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
The same reference numerals refer to the same parts throughout the various figures.
Referring now to the drawings, and particularly to
A pneumatic generating device 30 is connecting to the converter adapter 22 through an adapter tube 26, which is secured to the outlet of the pneumatic generating device 30 by an adjustable clamp 28. The adapter tube 26 is hollow, allowing fluid to travel therethrough. The adapter tube 26 has a first end diameter sized to receive the outlet of the pneumatic generating device 30 and a second end diameter sized to receive a tapered end 24 of the reducer 22, as best illustrated in
A large variety of connection systems can be used to connect the flanged adapter 14, the reducer 22, and the discharge tube 48 to the T-fitting 16. These connection systems can be, but not limited to, threaded connections, adhesive connections, pressure fitted connections, and clamped connections. All of the connections provide a fluid tight seal.
A discharge elbow tube 50 has a first end 52, a threaded bore 54 defined through the first end 52, and a second end 58. The first end 52 has a diameter smaller than the diameter of the discharge tube 48 end opposite the of the T-fitting 16 connection end. The first end 52 of the discharge elbow tube 50 is inserted into the discharge tube 48 until slot 49 is aligned with the threaded bore 54 of the first end 52 of the discharge elbow tube 50. The discharge elbow tube 50 is able to rotate freely with respect to the discharge tube 48. A threaded fastener 56 is inserted through slot 49 and driven into the threaded bore 54, thereby providing a rotational range of motion of the discharge elbow tube 50 with respect to the discharge tube 48. Alternately, the threaded fastener 56 can be a member extending out from the discharge elbow tube 50 adapted to be received by slot 49. The threaded fastener 56 can be driven further into the threaded bore 54 until a sufficient clamping force is produced between the threaded fastener 56, the discharge tube 48, and the discharge elbow tube 50, thereby locking the discharge elbow into a variety of angular positions with respect to the discharge tube 48.
As best illustrated in
A velocity tube 18 is connected to the tapered end 24 of the reducer 22. The velocity tube 18 can be connected to the tapered end 24 by a variety of connection systems such as, but not limited to, threaded connections, adhesive connections, pressure fitted connections, and clamped connections. All of the connections provide a fluid tight seal. The velocity tube 18 is hollow allowing for fluid to travel therethrough, and extends into the T-fitting 16 and terminates below the top oriented opening where the flanged adapter 14 and the rotary valve 40 is connected, as best illustrated in
A rigid discharge extension tube 60 or a flexible discharge extension tube 62 is removably connected the second end 58 of the discharge elbow tube 50. The discharge tubes 60 and 62 have a diameter larger than the diameter of the second end 58 of the discharge elbow tube 50. A nozzle 64 is removably connected to the free end of the discharge extension tubes 60 and 62, and is able to rotate with respect the discharge tubes 60 and 62. The discharge tubes 60 and 62, and the nozzle 64 are hollow, allowing fluid to travel therethrough. The nozzle 64 can be of any desired configuration, such as an angled nozzle, a flattened nozzle, a spreader nozzle, or the like. The discharge extension tubes 60 and 62 allow the user to remotely dispense the particulate material from the hopper 12 to, for example, an overhead animal feeder, a silo, a trough, or onto the ground.
The pneumatic generating device 30, reducer 22, T-fitting 16, hopper 16, discharge tube 48, discharge elbow tube 50, and discharge extension tubes 60 and 62 are supported on a support frame 70. The support frame 70, as best illustrated in
The pneumatic particulate dispensing system 10 is designed as a lightweight system for hunters to fill feeders with corn, protein, or the like. It is designed so that a single user could fill the feeders at remote locations. The hitch insert 72 can be adapter to fit any standard vehicle receiver hitch. The pneumatic particulate dispensing system 10 once attached to a vehicle through its hitch assembly, can dispense a variety of particulate material onto any surface travelable by the vehicle, such as dispensing salt onto to roadways, or dispensing seeds onto the farm lands.
In use, it can now be understood that a user would assemble the pneumatic particulate dispensing system onto the support frame and connect the pneumatic particulate dispensing system to the hitch assembly of a vehicle. The user would then rotate the valve cap to correspond to the amount of particulate material the user wishes to be dispensed into the airflow. The user would then fill the hopper with the desired particulate material. The proper discharge extension tube is then attached to the second end of the discharge elbow tube and the proper nozzle is chosen which corresponds to the labor that is to be performed. The pneumatic generating device would then be activated and the user would position the discharge elbow tube and the discharge extension tube to its proper operating position.
An example of such a use would be the filling of animal feeders by hunters. The hunter would assemble the pneumatic particulate dispensing system onto the support frame and connect the pneumatic particulate dispensing system to the hitch assembly of a vehicle. The hunter would adjust the valve cap and fill the hopper with the desired animal feed. The hunter would drive vehicle out to the location of the animal feeder and position the pneumatic particulate dispensing system near the animal feeder. The hunter would then activate the pneumatic generating device and position the discharge elbow tube and the discharge extension tube so as to allow the animal feed to dispense out the nozzle and into the animal feeder.
While a preferred embodiment of the pneumatic particulate dispensing system has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
